Chiasmus

Definition: Chiasmus is a rhetorical device where one clause is repeated, but in a reverse order. Most of the time, the clause uses the same grammar and word choice, but just in a reversed way. However, sometimes the clause or concept can be slightly modified when reversed.

Example: “The instinct of a man is to pursue everything that flies from him, and to fly from all that pursues him.” (Voltaire)
